TECHNICAL FIELD

The invention relates to medicine, namely, to the solutions used for hemostasis.

BACKGROUND ART

A liquid foaming hemostatic agent containing protein as a foaming component and fibrinogen as the active substance has been commonly known; the preparation may also include a coagulation-accelerating agent, US2014161738 (A1), published on 12 Jun. 2014.

The disadvantage of this solution is the low efficiency of hemostasis, and the lack of analgesic effect.

Another commonly known hemostatic composition is a powder comprising collagen in the form of fibers, and at least one monosaccharide; the composition may also contain a mixture of coagulants and glucosamineglucans, US2014023714 (A1), publ. Jan. 23, 2014.

This solution does not produce an analgesic effect, and in some cases may intensify the pain when applied to the wound.

There is another commonly known hemostatic agent intended mainly for use in dentistry. The composition is a hydrophilic paste comprising % wt: 5-15 aluminum chloride, 2-15 kaolin, 10-20 structurant, 50-70 water, 0-20 humectant; the total amount of water and humectant is 55-75% of the total weight of the composition; US2014348921 (A1), publ. Nov. 27, 2014.

This composition has a satisfactory hemostatic effect, but its use is generally limited to dentistry; the composition does not produce any analgesic effect.

Another commonly known hemostatic agent is Ferric Subsulfate (trade name: AstrinGyn), which is a solution of iron salts 259 mg/g, http://www.drugs.com/ppa/ferric-subsulfate.html, Dec. 8, 2014.

This preparation, which is adopted as a prototype of the claimed invention, has pronounced hemostatic properties at small dimensions of the wound surface, but provides no local anesthetic effect.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an efficient haemostatic preparation ensuring a significant analgesic effect.

Since the practice of medicine shows that in most cases bleeding is accompanied by pain, the task of creating effective hemostatic drugs with analgesic effect is both important and vital.

According to the invention, the hemostatic agent represents a polyammonia methanediamine chloride of the following general formula:

where: n=1-20, m=1-10, at that n×m≧8.

The hemostatic agent may be applied in the form of a 0.01-10% aqueous solution. An aqueous solution of the preparation can be used for impregnation of materials used for bleeding arrest, suture material, bandaging material. The hemostatic agent may be used in the composition of a retraction cord, adhesive pastes, vaginal and rectal suppositories, creams, gels, as well as used with microchips that provide slow release of the preparation. The preparation can also be used in eye drops, eye ointments, and lubricants applied to the surface of the catheter. The drug can be used in endodontic treatment, may be injected into a polymer sealer for root canal obturation, as well as locally—by means of electrophoresis. The hemostatic agent may be used in conjunction with a gel based on aluminum sulphate or silver solution, and also with a polysaccharide haemostatic system.

The claimed solution was prepared as follows.

Example 1

n=10, m=1.

Into a three-necked 1 liter flask equipped with an inert gas supply tube, a thermometer and a gas outlet tube 95.5 g (1 mole) of hydrochloride aminemethanediamine (46.7 wt. %), and 104.4 g (0.90 mol) of 1.6-diaminohexane (DH) (51.1 wt. %) were introduced, after which the flask was purged with nitrogen. The contents of the flask were heated to 100° C. and stirred until complete dissolution. Then 4.5 g (0.09 mol) of hydrazine hydrate (HH) (2.2 wt. %) were added, the solution was stirred and placed into an air thermostat, and the gas outlet tube was connected to the receiver for ammonia capturing. Then, while purging with nitrogen at a rate of 30-40 ml/min, the reaction mixture was heated with gradual removal of water and ammonia for 1 hour adjusting the temperature of the mass to the constant reaction temperature of 190° C. Reaction temperature was maintained for 30 minutes, while the system was purged with nitrogen. Thereafter, the system was cooled to 160° C. and the hot syrupy mixture was poured onto a metal pan and cooled, obtaining 169.9 of product in the form of a solid, almost colorless transparent substance.

Example 2

The hemostatic agent was prepared analogously to Example 1, with n=5, m=2, DH=0.85 mole, HH=0.17 mole.

Example 3

The hemostatic agent was prepared analogously to Example 1, with n=10, m=2, DH=0.9 mole, HH=0.09 mole.

Example 4

The hemostatic agent was prepared analogously to Example 1, with n=10, m=5, DH=0.9 mole, HH=0.09 mole.

Example 5

The hemostatic agent was prepared analogously to Example 1, with n=15, m=10, DH=0.93 mole, HH=0.063 mole. The reaction temperature and the holding time according to Examples 1-5 are given in Table 1.

The resulting polymer is non-stereoregular, i.e. the mutual arrangement of alternating components of hydrazine and 1.6 of diamine-hexane in the polymer chain may be arbitrary. But the average proportion of these components determined by the proportion of the initial reagents has a constant value in each example. The resulting material has a nanostructure.

The nanostructure is determined by the methods of dynamic light scattering using a Malvern Instruments Nanosizer Nano-ZS particle size analyzer and a FEI Tecnai G212Cryo12 transmission electron microscope enabling tp cool the samples at the boiling point of liquid nitrogen.

By the dynamic light scattering method was found that at the preparation concentration of 0.05 mg/ml the solution contains globules by the size of 10-15 nm. An electron-microscopic examination also revealed globules by the size of 10-15 nm.

The applicant has not found any sources of information containing data on technical solutions identical to the claimed invention, which enables to conclude that the claimed invention conforms to the criterion “Novelty” (N).

The applicant has not found any sources of information containing data on the technical result achieved by means of the invention, that is providing both an effective hemostatic effect and a significant analgesic effect. This, in the applicant's opinion, indicates that the invention conforms to the criterion “Inventive Step” (<<IS>>).

PREFERRED EMBODIMENT

The effectiveness of the claimed hemostatic agent with analgesic effect is shown in the following examples.

I. Examination of Hemostatic Activity of the Preparation Example 1.1

The influence of the claimed substance on the hemostatic function was examined in rabbits of both sexes weighing 2000-4000 g. The experiments were carried out under general anesthesia. The animals underwent a laparotomy with a section made along the white line of the abdomen. The intestine was exteriorized into the wound and limited by wipes moistened with 0.9% sodium chloride solution (temperature 370° C.), as well as the front surface of the liver. A superficial wound of the liver by the area of 1.5 cm² and the depth of 0.1 cm was inflicted by means of a razor.

Arrest of the capillary-parenchymal bleeding was carried out by uniform application of a 1% solution or a spray of the claimed substance on the entire area of the wound surface. At that, iron subsulfat was used for comparison of the bleeding arrest time. Hemostatic activity was evaluated by the change of the bleeding intensity. The results are shown in Table 2.

The data in Table 2 show a higher hemostatic activity of the claimed substance in comparison to the prototype.

Example 1.2

To evaluate the efficiency of the claimed substance at impregnation of the bandaging material used for hemostasis, a sterile swab was impregnated with a solution of the claimed substance in a concentration of 0.01% to 10%, and then dried. A conventional gauze swab was used for reference in order to compare the bleeding arrest time. An animal model was used in the experiment, as described in Example No. 4. Hemostatic activity was evaluated by the change of the bleeding intensity. The results are shown in Table 3.

Example 1.3

To evaluate the efficiency of the claimed substance at impregnation of suture materials used in surgery, a resorbable suture material (catgut) and a non-resorbable suture material (nylon) were impregnated with a 5% solution of the claimed substance. The same suture material, not impregnated with the claimed substance, was used for reference in order to compare the bleeding arrest time. An animal model (rabbits) was used in the experiment, in which the anesthetized animals underwent an incision (2 cm long and 0.5 cm deep) made in each rabbit's paw. Hemostatic activity was evaluated by the change of the bleeding intensity. The results are shown in Table 4.

II. Determination of Anesthetic Activity Example 2.1

A study to determine anesthetic activity was carried out in unanesthetized rabbits, which were placed in a special box with a hole to restrain the animal's head. The study was conducted to determine the threshold of sensitivity of the rabbit's eye to a tactile impact. For this purpose, a thin metal wire was used without injuring the cornea. The examined compound and the reference drug (oxybuprocaine) were administered into the conjunctival sac of the rabbit's eye in the form of a 0.5% aqueous solution with the total volume of up to 0.4 ml. Determination of topical anaesthesia was performed starting from the 1st minute of the study. The absence of the blinking reflex for 1 min (100 touches) was considered as an indicator of full anesthesia. Based on the collected data reflecting the changes in corneal sensitivity under the influence of the drugs, the beginning, the duration of complete (100%) anesthesia and the total duration of anesthesia were determined.

The relative activity of the tested compounds was calculated according to the Valet equation. The Rainier index is 852.4 for the claimed preparation and 63.5 for the reference preparation. The duration of anesthesia was 234 minutes for the claimed preparation and 24 min for oxibuprocaine.

Example 1.8
